Yup I liked the original B12 too. I liked the format, I was excited about getting to play the then-dominant Huskers, and I even liked the idea of having OU as a conference game.
But I was born and raised with the SWC. If money hadn't completely changed the sport, I'd have been delighted to stick with the SWC and its bowl affiliations from about 1983, and I really liked all of the other conferences and their bowls as well. The focus back then wasn't solely on the national championship, it was all about beating your rivals, winning the conference, and getting to a good bowl game. I enjoyed college football a lot more then, than I do now.
But there's no turning back time, so we have to take what we're given and find the best in it. Or, alternatively, leave it, if we no longer find it compelling.
